Two hundred and thirty one experts have been recruited to the NNR2023 project and been directly involved in the development of NNR2023 (see appendix 1). In addition, a large number of scientists have also contributed with important input through 59 public consultations. Their names and input as well as the responses from the NNR2023 Committee will be published in a separate report. Finally, consultations with scientific committees among health authorities in many countries in Europe, America, Asia and Oceania have also contributed significantly to the report. Thus, while the NNR2023 Committee is solely responsible for the text in the final NNR2023 report, we greatly appreciate and acknowledge the essential input from many hundred scientists and international external experts.
